Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image forming apparatus such as a copying machine, a printer, a facsimile machine, or a combination thereof, and more particularly to an apparatus capable of attaching an optional device to the apparatus body later.
[0002]
[Prior art and problems to be solved by the invention]
Various proposals have conventionally been made on the cover structure of an image forming apparatus in which an optional device can be attached to the apparatus main body. For example, in the image forming apparatus disclosed in Japanese Patent Laid-Open No. 10-133443, the main body of the exterior cover is proposed. When installing optional equipment, cut out the cutout to open an opening for mounting on the exterior cover, and show independent functions such as a hook shape and a shape that can become a pen tray in advance. It has a shape that allows it to be cut, so that the cut-out portion does not have to be discarded, thus saving resources and reducing waste.
[0003]
However, if a cut in a perforation or the like is made in a part of the exterior cover for optional installation and then cut off from the cut for retrofitting optional equipment, then it is used as a separate functional product as described above. However, if it is impossible to regenerate and is easily lost when removed, there is a problem in storage, and if the optional equipment once installed is to be removed at a later date, the cut-out part should be removed. There was a problem that it was not possible to cover the appearance without much damage.
[0004]
The image forming apparatus according to the present invention has been made in view of the above-described conventional problems and employs a partial cover, but can be used without discarding the partial cover regardless of whether or not optional equipment is attached. Accordingly, an object of the present invention is to provide an exterior cover that is capable of being configured so that there is no risk of loss and that is necessary and sufficient for safety and appearance.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, an image forming apparatus according to a first aspect of the present invention is an image forming apparatus in which an optional device can be attached to the apparatus main body, and an exterior cover corresponding to a portion to which the additional optional device is attached in advance. The portion is a partial cover that can be attached to and detached from the exterior cover, and the partial cover has a portion extending from the surface of the partial cover to the depth direction of the apparatus main body at the top and bottom or left and right edges, The attachment portion of the partial cover has at least one shape part to which the partial cover can be attached and detached, and the partial cover is reversed in the up / down or left / right direction when the optional device is not installed and when the optional device is installed. attachable and then, by attaching to the apparatus body of the partial covering, it is the option device when attached to the apparatus main body above By the partial cover and the outer cover to Okimoto body can be provided an opening between said two covers, the optional device when not attached to the apparatus main body, characterized in that it is possible to close the opening.
[0006]
Those according to the second aspect is the image forming apparatus according to claim 1, a portion of the portion extending to the back bound direction tongue-like upper Symbol partial covering, fitting the tongue piece-shaped portion of the exterior cover wear available-parts comprises a said Oh Rukoto with tongue-like recess extending and corresponding to the shape of the tongue-shaped portion of the partial covering in the depth direction of the device the body from the surface of 該Gaiso cover To do.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a front perspective view showing a state in which an apparatus main body 1 of an embodiment of an image forming apparatus according to the present invention is set on a paper supply bank 2 which is an optional apparatus. 2 is a perspective view of the vicinity of the connectors of the apparatus main body 1 and the paper supply bank 2 of FIG. 1 as viewed from the back side.
[0009]
In the figure, reference numeral 3 denotes a partial cover, which is attached to a required portion of the exterior cover 5 on the back side of the apparatus main body 1 with screws 4. A connector 6 is provided near the inner side of the partial cover 3 to connect a harness 7 when the paper feed bank 2 is attached later.
[0010]
The partial cover 3 is provided with a tongue piece 3a projecting in the depth direction of the apparatus main body 1 at one edge in the vertical direction. In a standard state where the paper supply bank 2 is not mounted, the partial cover 3 is turned upside down from FIG. The cutout portion 5a provided at the corresponding portion of the outer cover 5 is closed with the tongue piece portion 3a.
[0011]
When the paper supply bank 2 is combined with the apparatus main body 1 that is already in use as a retrofit optional device, after the paper supply bank 2 is placed on the apparatus main body 1, a required part such as the back side of the apparatus main body 1 is provided. After removing the partial cover-3 provided in the sheet feeder 2, the harness 7 is taken out from the sheet feeding bank 2, and the connector 7a of the harness 7 is inserted into a predetermined position, part, or device such as the connector 6 on the apparatus body 1 side. As a result, the apparatus main body 1 and the paper supply bank 2 are electrically connected. Thereafter, the partial cover 3 is reset to the exterior cover 5 as shown in FIG. At this time, since the tongue piece portion 3a cannot be put into the cutout portion 5a, the cutout portion 5a serves as an inlet for the harness into the apparatus main body 1, and the harness 7 interferes with the attachment of the partial cover 3. Absent. Of course, since the tongue piece 3a protrudes into the apparatus main body 1 in this state, the tongue piece 3a must be configured not to interfere with the internal devices.
[0012]
【The invention's effect】
As an image forming apparatus according to the present invention has been described above, pre additional options some detachable part cover of the outer cover corresponding to the site of attachment of the device - and, attachment to the device body portion covering this Depending on the method, an opening can be provided between the two covers by the partial cover and exterior cover when the optional device is attached to the device main body, and the opening can be blocked when the optional device is not attached to the device main body. so I was able to so, in case of mounting from after the optional equipment, a large hippopotamus of the apparatus main body - it is not necessary to remove the, of course, is that the workability is good Kunar, though a partial cover mounting of optional equipment, in non-mounted always Okeru attached to the apparatus body without, or worse Remove and discard the part partial cover, also lost or That you it also eliminated, and therefore there is an effect that can also be a necessary and sufficient cover construction safety above and appearance.
